Question: Has J.J. Abrams mapped out the entire story for Lost? If so, how many seasons can we expect?

Answer: Well, according to Damon Lindelof, he and J.J. "absolutely have a master plan." And if they stick to it, the show will last "somewhere in the neighborhood of four or five seasons. I don't think you could sustain it that much longer without people getting really frustrated."
